There is one person I don't see on the list: Terry. That is the person I would most like to see interviewed. I know he's the owner and pillar of this site, and probably won't, but I always wonder things like: What prompted you to even start Fun Trivia? How gratifying is it to work with so many wonderful volunteers? etc.
If you can't sleep, then get up and do something instead of lying there worrying. It's the worry that gets you, not the lack of sleep.
